PAUL FOSS, OF CHICAGO, ILLINOIS.

AUTOMATIC BLANK-FEED FOR following, when taken in connection with the drawings accompanying and forming apart "hereof, is a full and complete description,

sufiicient to enable those skilled in the art to which it pertains to understand, make, and

use. the same.

This-invention relates to automatic canbody-making machines; and the object of the-invention is to obtain an apparatus. by means of which theblanks from which can bodies are being made on the machine may be automatically fed to such machine from a pile of blanks for can-bodies which are placed 1n proper position on this apparatus.

A further object of the invention is to obtain an automatic can-body-bIank-feeding machine which will be economical in construction and not liable to get out of order.

- In the drawings referred to as forming; a part of this specification, Figure 1 is a to plan view of an apparatus embodying tlns invention. Fig. 2 is an end elevation of an apparatus embodying this invention.. Fig. 3 is asectional view on line 3 3 of Fig. 2 viewed in the direction indicated by the arrows. Fig. 4 is aside elevationyon an enlarged scale, of a ortion of a longitudinally-movable slide orming an element in the a paratus embodying this invention; and F1g.5 is a lan view, on an enlarged scale, of a portion'o the longitudinally-movable slide shown in Fig. 4. A reference-letter'applied to designate a given part is used to indicate such part throughout the several figures of 'the drawings wherever the same appears.

A A constitute the base of the a paratus. a a are grooves in base A A, in whic grooves the longitudinally-movable bars B B are placed and arranged to slidefreely.

, C is a bar underneath art A of the base.

Bar G is secured, as by t e bolt indicated in dotted lines C in Fig. 3, to bars B B.

D D are pulleys rotatably mounted in base A, so that the eripherythereof extends a slight distance ve the upper surface of the base A. v i

E, Fi .3,re resents can-body blanks rest-' ing on t e pul eys D D between the guides F F and G G. Guide F is arranged so that the Specification of Letters Patent. I Application filed December 16, 1906. Serial Nb. 291.847-

bottom one of the blanks thereunder.

ff are lugs on the front side of the guide F.

H H are adjustable fingers on guide F, respectively adjustable by means of bolts 9 g in lugs f f and secured in an adjusted position by bolts h h.

I I are pulleys (see Fig. 2) rotatably mounted on base A underneath the adjustable fingers H H. FingersH H are adjusted relative to theperiphery of the pulleys II, respectively, so that a single can-body blank may pass between them or be forced between giem by the longitudinally-movable bars The longitudinally-movable bars B B are respectively provided with the recesses b. therein on the parts thereof which move underneath the pile of can-body blanks between the several" guides F F and G G. In the recess b of each one of the bars B B there is piv- "otally mounted the lever K.. There is only slight movement required of the lever K, and I prefer to shape the end thereof at'k to constitute the pivot on which it turns, such pivot fitting into a corresponding recess b of recess b.

L is a spring secured to the forward end of lever K, as by pin Z, and M is a set-screw by means of which the free end of the spring L is adjusted adjacent to the vertical wall m to be the rightdistance below the upper faceof the bar B, so that such vertical wall m'will engage with one, and one only, of the can-body E may be pushed blanks under which such vertical bar Bis J tudinally-movable bars such lower or bottom one'of the can-body blanks will be forced un-' derneath theadjusted fingers H H, between such fingers and the can-body machine.

The bars B B, orsome of them, extend to the can-body-making machine, so that when a can-body blank is forced out from this. ap-

paratus in the manner last above described on such bars B B such can-body blank is thereby delivered to the can-body-making machine in substantially the same position can-body blanks are now fed by hand to such machine.

Motion is-impat. ed to the several longitupulleys I I, and fed to the.

the bottom one of such can-body blanksv down on the movable bars B B, so that the lever K will engage with such can-body blank as such bars are longitudinally moved underneath the pile in the operation of the machine. v v

- O is a spring holding the lever K up against the pile of can-body blanks.

m is the vert'cal Wall of the forward end ofther'ecessh' gHaving thus/described my invention, what I claim as new, and desire to secure. Let-- 'ters Patent, is v r 1. The-combinationof a base, guides; on the base to form areceptacle for a. pileof canbody blanks, the lower edge of the guide forming the forward Wallof the receptacle I raised above the base to ermit the bottom one of the pile of can-bod blanks placed in the receptacle to be forced from under'such pile and out ofthe receptacle, adjustable fin gers on such forward guide, means to secure, the respectivefingers in an adjustedposition, rollers rotatably mountedon thebase to @0- act with the adjustable fingers, respectively,

with means to force blanks from the recepta-' cle between the fingers and the coacting roll? I I cure the adjustablefin. ers in an adjusted oers; substantially as described.

2. The combination of a base, gufdeson the base to form areceptacle for a'pile of canbody blanks,- the lower edge of the forward guide not extending to contact with the base, an adjustable finger onv such forward guide, means to secure the adjustablefirger in an adjusted position relative to the base, long1tudi11ally-movable bar and levers respectively placed in mi h longitudinallymovable bars to engage with the bottom one of the pile of can-body blanks and, force the 'same out from under the 'pile and underneath the lower edge of the forward guide.

3. The combination of a base, guides on the base to form a receptacle for a pile of canbody. blanks the lower edge of the forward guide not in contact with the base, an adjustable fi" ger on such forward guide, means to i secure the adjustable finger in an adjusted position relative to the base, longiand force a can-body blank out from under the pile thereof and underneath the lower edge of the forward guide.

4. The combir ation of a base, guides on the base toform a receptaclefor a pile of can body blaf...ks, the lower edge of the/forward guide not extending to contact with the base, adjustable fingers on such forward guide, .meansto secure the respectiveadjustable gers in an adjusted positionrelative to the base, rollers rotatably mouzited on the base to coact with the adjustable firgers, respectively, longitudinallymovable bars, and levers respectively placed'in such longitudilnallyrmovable'bars to engage with the bottom one of the pile of'can-body blanks ardforce the same out from under the pile and underneath the lower edge ofthe forward guide.

5. The combination of abase, guides on the base to form a receptacle for a ile of canbody blanks the lower edge of t e forward igluide not in contact with the base, adjustable gers on such forward guide, means to sesition relative to the ase, rollers rotata 1y mounted on thebase to coact with the adjustable fingers, respectively, longitudinallymovable bars provided respectively. with a recess therein, levers pivotally mounted in the recess such lon itudinally-movable 'bars, respectively, such evers rovi-ded' with a vertical wall to-ergagewit ,thebottor'n' one of the pile oif can-body blanks and adjustable 'meclganis'm to vary the operative height of the vertical Wall, and means to ac tuate the horizontally-movable bars, and
